binfmt_elf: switch to new creds when switching to new mm
We used to delay switching to the new credentials until after we had
mapped the executable (and possible elf interpreter). That was kind of
odd to begin with, since the new executable will actually then _run_
with the new creds, but whatever.
The bigger problem was that we also want to make sure that we turn off
prof events and tracing before we start mapping the new executable
state. So while this is a cleanup, it's also a fix for a possible

raid5-cache: fix a deadlock in superblock write
There is a potential deadlock in superblock write. Discard could zero data, so
before discard we must make sure superblock is updated to new log tail.
Updating superblock (either directly call md_update_sb() or depend on md
thread) must hold reconfig mutex. On the other hand, raid5_quiesce is called
with reconfig_mutex hold. The first step of raid5_quiesce() is waitting for all
IO finish, hence waitting for reclaim thread, while reclaim thread is calling
this function and waitting for reconfig mutex. So there is a deadlock. We
workaround this issue with a trylock. The downside of the solution is we could
miss discard if we can't take reconfig mutex. But this should happen rarely
(mainly in raid array stop), so miss discard shouldn't be a big problem.

kernfs: don't depend on d_find_any_alias() when generating notifications
kernfs_notify_workfn() sends out file modified events for the
scheduled kernfs_nodes. Because the modifications aren't from
userland, it doesn't have the matching file struct at hand and can't
use fsnotify_modify(). Instead, it looked up the inode and then used
d_find_any_alias() to find the dentry and used fsnotify_parent() and
fsnotify() directly to generate notifications.
The assumption was that the relevant dentries would have been pinned
if there are listeners, which isn't true as inotify doesn't pin
dentries at all and watching the parent doesn't pin the child dentries
even for dnotify. This led to, for example, inotify watchers not
getting notifications if the system is under memory pressure and the
matching dentries got reclaimed. It can also be triggered through
/proc/sys/vm/drop_caches or a remount attempt which involves shrinking
dcache.
fsnotify_parent() only uses the dentry to access the parent inode,
which kernfs can do easily. Update kernfs_notify_workfn() so that it
uses fsnotify() directly for both the parent and target inodes without
going through d_find_any_alias(). While at it, supply the target file
name to fsnotify() from kernfs_node->name.

thunderbolt: Fix resume quirk for Falcon Ridge 4C.
The quirk 'quirk_apple_wait_for_thunderbolt' did not fire on Falcon
Ridge 4C controllers with subdevice/subvendor set to zero. This lead
to lost pci devices on system resume.
Older thunderbolt controllers (pre Falcon Ridge) used the same device id
for bridges and for the controller. On Apple hardware the subvendor- &
subdevice-ids were set for the controller, but not for bridges. So that
is what was used to differentiate between the two. Starting with Falcon
Ridge bridges and controllers received different device ids.
Additionally on some MacBookPro models (but not all) the
subvendor/subdevice was zeroed.
Starting with
a42fb351c (thunderbolt: Allow loading of module on recent
Apple MacBooks with thunderbolt 2 controller) the thunderbolt driver
binds to all Falcon Ridge 4C controllers (irregardless of
subvendor/subdevice). The corresponding quirk was not updated.
This commit changes the quirk to check the device class instead of its
subvendor-/subdeviceids. This works for all generations of Thunderbolt
controllers.

lkdtm_rodata_do_nothing() is an empty function which is generated in
order to test the non-executability of rodata.
Currently if function tracing is enabled then an mcount callsite will be
generated for lkdtm_rodata_do_nothing(), and it will appear in the list
of available functions for function tracing (available_filter_functions).
Given it's purpose purely as a test function, it seems preferable for
lkdtm_rodata_do_nothing() to be marked notrace, so it doesn't appear as
traceable.
This also avoids triggering a linker bug on powerpc:
https://sourceware.org/bugzilla/show_bug.cgi?id=20428
When the linker sees code that needs to generate a call stub, eg. a
branch to mcount(), it assumes the section is executable and
dereferences a NULL pointer leading to a linker segfault. Marking
lkdtm_rodata_do_nothing() notrace avoids triggering the bug because the

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Allow nf_tables reject expression from input, forward and output hooks,
since only there the routing information is available, otherwise we crash.
2) Fix unsafe list iteration when flushing timeout and accouting objects.
3) Fix refcount leak on timeout policy parsing failure.
4) Unlink timeout object for unconfirmed conntracks too
5) Missing validation of pkttype mangling from bridge family.
6) Fix refcount leak on ebtables on second lookup for the specific

Kees Cook [Wed, 10 Aug 2016 23:28:09 +0000 (16:28 -0700)]
seccomp: Fix tracer exit notifications during fatal signals
This fixes a ptrace vs fatal pending signals bug as manifested in
seccomp now that seccomp was reordered to happen after ptrace. The
short version is that seccomp should not attempt to call do_exit()
while fatal signals are pending under a tracer. The existing code was
trying to be as defensively paranoid as possible, but it now ends up
confusing ptrace. Instead, the syscall can just be skipped (which solves
the original concern that the do_exit() was addressing) and normal signal
handling, tracer notification, and process death can happen.
Paraphrasing from the original bug report:
If a tracee task is in a PTRACE_EVENT_SECCOMP trap, or has been resumed
after such a trap but not yet been scheduled, and another task in the
thread-group calls exit_group(), then the tracee task exits without the
ptracer receiving a PTRACE_EVENT_EXIT notification. Test case here:
https://gist.github.com/khuey/
3c43ac247c72cef8c956ca73281c9be7
The bug happens because when __seccomp_filter() detects
fatal_signal_pending(), it calls do_exit() without dequeuing the fatal
signal. When do_exit() sends the PTRACE_EVENT_EXIT notification and
that task is descheduled, __schedule() notices that there is a fatal
signal pending and changes its state from TASK_TRACED to TASK_RUNNING.
That prevents the ptracer's waitpid() from returning the ptrace event.
A more detailed analysis is here:

bio_alloc() can allocate a bio with at most BIO_MAX_PAGES (256) vector
entries. However, the incoming bio may have more vector entries if it
was allocated by other means. For example, bcache submits bios with
more than BIO_MAX_PAGES entries. This results in bio_alloc() failure.
To avoid the failure, change the code so that it allocates bio with at
most BIO_MAX_PAGES entries. If the incoming bio has more entries,
bio_add_page() will fail and a new bio will be allocated - the code that

mm/usercopy: get rid of CONFIG_DEBUG_STRICT_USER_COPY_CHECKS
There are three usercopy warnings which are currently being silenced for
gcc 4.6 and newer:
1) "copy_from_user() buffer size is too small" compile warning/error
This is a static warning which happens when object size and copy size
are both const, and copy size > object size. I didn't see any false
positives for this one. So the function warning attribute seems to
be working fine here.
Note this scenario is always a bug and so I think it should be
changed to *always* be an error, regardless of
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS.
2) "copy_from_user() buffer size is not provably correct" compile warning
This is another static warning which happens when I enable
__compiletime_object_size() for new compilers (and
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS). It happens when object size
is const, but copy size is *not*. In this case there's no way to
compare the two at build time, so it gives the warning. (Note the
warning is a byproduct of the fact that gcc has no way of knowing
whether the overflow function will be called, so the call isn't dead
code and the warning attribute is activated.)
So this warning seems to only indicate "this is an unusual pattern,
maybe you should check it out" rather than "this is a bug".
I get 102(!) of these warnings with allyesconfig and the
__compiletime_object_size() gcc check removed. I don't know if there
are any real bugs hiding in there, but from looking at a small
sample, I didn't see any. According to Kees, it does sometimes find
real bugs. But the false positive rate seems high.
3) "Buffer overflow detected" runtime warning
This is a runtime warning where object size is const, and copy size >
object size.
All three warnings (both static and runtime) were completely disabled
for gcc 4.6 with the following commit:
2fb0815c9ee6 ("gcc4: disable __compiletime_object_size for GCC 4.6+")
That commit mistakenly assumed that the false positives were caused by a
gcc bug in __compiletime_object_size(). But in fact,
__compiletime_object_size() seems to be working fine. The false
positives were instead triggered by #2 above. (Though I don't have an
explanation for why the warnings supposedly only started showing up in
gcc 4.6.)
So remove warning #2 to get rid of all the false positives, and re-enable
warnings #1 and #3 by reverting the above commit.
Furthermore, since #1 is a real bug which is detected at compile time,
upgrade it to always be an error.
Having done all that, CONFIG_DEBUG_STRICT_USER_COPY_CHECKS is no longer
needed.

ARM: EXYNOS: Clear OF_POPULATED flag from PMU node in IRQ init callback
The Exynos PMU node is an interrupt, clock and PMU (Power Management Unit)
controller, and these functionalities are supported by different drivers
that matches the same compatible strings.
Since commit
15cc2ed6dcf9 ("of/irq: Mark initialised interrupt controllers
as populated") the OF core flags interrupt controllers registered with the
IRQCHIP_DECLARE() macro as OF_POPULATED, so platform devices with the same
compatible string as the interrupt controller will not be registered.
This prevents the PMU platform device to be registered so the Exynos PMU
driver is never probed. This breaks (among other things) Suspend-to-RAM.
Fix this by clearing the OF_POPULATED flag in the PMU IRQ init callback,
to allow the Exynos PMU platform driver to be probed. The patch is based
on Philipp Zabel's "ARM: imx6: mark GPC node as not populated after irq
init to probe pm domain driver".

xfs: track log done items directly in the deferred pending work item
Christoph reports slab corruption when a deferred refcount update
aborts during _defer_finish(). The cause of this was broken log item
state tracking in xfs_defer_pending -- upon an abort,
_defer_trans_abort() will call abort_intent on all intent items,
including the ones that have already had a done item attached.
This is incorrect because each intent item has 2 refcount: the first
is released when the intent item is committed to the log; and the
second is released when the _done_ item is committed to the log, or
by the intent creator if there is no done item. In other words, once
we log the done item, responsibility for releasing the intent item's
second refcount is transferred to the done item and /must not/ be
performed by anything else.
The dfp_committed flag should have been tracking whether or not we had
a done item so that _defer_trans_abort could decide if it needs to
abort the intent item, but due to a thinko this was not the case. Rip
it out and track the done item directly so that we do the right thing
w.r.t. intent item freeing.

clocksource/drivers/atmel-pit: Fix compilation error
The previous fix introduced a check against the ret variable which
is not defined, hence producing a compilation error:
linux/drivers/clocksource/timer-atmel-pit.c: In function ‘at91sam926x_pit_dt_init’:
linux/drivers/clocksource/timer-atmel-pit.c:264:2: error: ‘ret’ undeclared (first use in this function)
ret = clk_prepare_enable(data->mck);
^
linux/drivers/clocksource/timer-atmel-pit.c:264:2: note: each undeclared identifier is reported only once for each function it appears in
Add the missing the variable 'ret'.

The problem happens when you call ioctl(SNDRV_TIMER_IOCTL_CONTINUE) on a
completely new/unused timer -- it will have ->sticks == 0, which causes a
divide by 0 in snd_hrtimer_callback().

net: smc91x: fix SMC accesses
Commit
b70661c70830 ("net: smc91x: use run-time configuration on all ARM
machines") broke some ARM platforms through several mistakes. Firstly,
the access size must correspond to the following rule:
(a) at least one of 16-bit or 8-bit access size must be supported
(b) 32-bit accesses are optional, and may be enabled in addition to
the above.
Secondly, it provides no emulation of 16-bit accesses, instead blindly
making 16-bit accesses even when the platform specifies that only 8-bit
is supported.
Reorganise smc91x.h so we can make use of the existing 16-bit access
emulation already provided - if 16-bit accesses are supported, use
16-bit accesses directly, otherwise if 8-bit accesses are supported,
use the provided 16-bit access emulation. If neither, BUG(). This
exactly reflects the driver behaviour prior to the commit being fixed.
Since the conversion incorrectly cut down the available access sizes on
several platforms, we also need to go through every platform and fix up
the overly-restrictive access size: Arnd assumed that if a platform can
perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
size needed to be specified - not so, all available access sizes must
be specified.
This likely fixes some performance regressions in doing this: if a
platform does not support 8-bit accesses, 8-bit accesses have been
emulated by performing a 16-bit read-modify-write access.
Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
accesses, which was broken by the original commit.

Saeed Mahameed says:
====================
Mellanox 100G mlx5 fixes 2016-08-29
This series contains some bug fixes for the mlx5 core and mlx5
ethernet driver.
From Saeed, Fix UMR to consider hardware translation table field
size limitation when calculating the maximum number of MTTs required
by the driver. Three patches to speed-up netdevice close time by
serializing channel (SQs & RQs) destruction rather than issuing and
waiting for hardware interrupts to free them.
From Eran, Fix ethtool ring parameter reporting for striding RQ layout.
Add error prints on ETS validation failure.
From Kamal, Fix memory leak on error flow.
From Maor, Fix ethtool steering priorities number.

net/mlx5e: Fix ethtool -g/G rx ring parameter report with striding RQ
The driver RQ has two possible configurations: striding RQ and
non-striding RQ. Until this patch, the driver always reported the
number of hardware WQEs (ring descriptors). For non striding RQ
configuration, this was OK since we have one WQE per pending packet
For striding RQ, multiple packets can fit into one WQE. For better
user experience we normalize the rx_pending parameter (size of wqe/mtu)
as the average ring size in case of striding RQ.
